output=silent (crontab mode)

[skob]

Is your feature request related to a problem? Please describe.
when using alerta-cli with crontab, extra-output send annoyed emails. It's possible to suppress output by > /dev/null , but it is not good solution

Describe the solution you'd like
plz add --output=silent for crontab :-)

Thanks for raising this issue. Is this something you think you could fix yourself?

Hi, @skob , why using > /dev/null is not a good solution?

[skob]

Because you can loose output from cronjob and you can’t control this behavior

@skob Which alerta commands are you talking about? And what output are you suggesting should be silenced from those commands?

I've just checked alerta housekeeping and it doesn't seem to generate any output unless there's an error.

The click progress bar doesn't render in a progress bar unless your tty has stdout ...
""" By default, this progress bar will not be rendered if the file is not a terminal.
I've modified the CLI to output errors to stderr and so the earlier suggested work-around of piping to /dev/null should be sufficient.
